lM PROV'EM'E NT IN 'PLOWS.

Specification forming part of Letters Patent No. 3 1,452, dated February 19, 1861.

Figure 1 shows a top view of my improved plow. Fig. 2 is a side elevation of the same, with a portionof the beam and mold-board broken out to show some of the parts more clearly. Fig. 3 is an end view of theimproved 'elevis, showing the parts in two positions.

Fig. 4 is a perspective sectional view of the plow, showing the construction of the same.

Similar letters of reference indicate correspondin g parts in the several figures.

To enable those skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The first part of my invention relates to the plow-body, which is composed of four principal parts viz, the sole-plateA, share A, point B, and landside 13, all of which form one piece, the mold-board O, the colter-plate D, and the landside-wing D. These four parts are put together in the following manner: The moldboard 0 is secured by bolts to the enlargement (standard portion) a and to the handle F. The cutter D is then attached to aslotted plate, I), on thelandside bya dovetailtenon,c, (shown clearly in Fig. 4,) which tenon entersthe lower portion of the slot, and is then pushed up so as to Wedge itself tightly and hold securely to the plate b. The cutter-plate has two cuttingedges, either of which may be used, and by reversing the plate when one edge wears dull a newcutting-edgemaybe presented. Thewing D is attached behind the cutterDby a tenon, c, in thesame manner as D is attached. The sole plate, share, point, and landside bar, which have been described as one piece, are now secured by a bolt, 6, that passes up through the sole-p1ate A and through the beam G and receives a nut on its upper end, as shown in 4 Fig. 2, by a bolt that passes through a lip, d,

at the heel of the landside bar B, (shown in Fig. 4,) and through the lower end of handle F, and through the back part of the landside wing D, and by two bolts, 0 e, that pass through the sole-plate Aand through the lower edge of the mold-board O. The four parts forming the plow-body are in this manner firmly secured together in their proper places, and as the plates D D rest on the top of the landside-bar B, they are prevented from slipping down without first removing the bottom of the plow.

The second part of my invention relates to a novel manner of holding the plow down and keeping it steady, and to prevent the jarring and concussions occasioned by attaching the draft-chain rigidly to the clevis. H is adraftrod that passes through an adjustable slotted bar attached to the clevis, as will be hereinafter described, and is carried along under the beam G behind the standard a, and hooks-into an adjustable coupling-link thatis attached to an arm of the bent lever I. Said lever has its fulcrum in the beam G, as shown in Fig.2, and its upper arm is connected to a spring, J, by a short stirrup, g. The spring J is simply a stout strip of steel-plate that is secured at one end by bolts which secure the standard to the beam. Its other end is allowed to play on a face-plate near the rear end of the beam G. The beam is attached to the ring on the front end of rod H, and it will be seen that the draft will be transferred from the clevis or end of the beam behind the standard a, so that while the plow is held steady by the beam it will be held down. to its work with greater or less force, according to the position of the adjustable coupling-link with relation to the bottom of the beam. Besides this the draft will be upon the spring J, which takes oft much of the jar and concussions, which in some kinds of plowing is very hard on' the horses.

Theinvention relates, thirdly, to a novel ar rangement for clearing the plow of grass, &c.,

and preventing its clogging up at the angle formed by the standard and under side of the beam. K is a rod with a crescent-shaped fork on'one end, which is attached to the righthand side of the beam G, so as to be free to receive an alternate reciprocating motion. At the rear end of the rod K is attached a crank, h, which receives its motion from a tractionwheel, L, through the medium of a connect ing-ro d, L. This motion of the wheel gives to the rod K at each revolution of the wheel a forward and downward thrust, which pushes off grass or other obstructions from the front part of the plow, and in this manner lessens the draft of the plow to a great extent. The wheel L is hung in such a manner by the swinging rod N and rod P that the attendant can raise this wheel free from the ground, and thus stop the motion of the clearerRwhile the plow is in motion.

The clevis is peculiarin its construction, consistin g of two circular bevel-spurred plates, S S, one of which is like a bevel-spurred wheel, and this is securely bolted to the end of the beam G, and the other is a spurred ring with the teeth on the inside of this ring. 011 the outside of the ring S is formed a dovetail groove, into which slides aslotted bar, k, which is secured rigidly to the ring by the screw n,

that passesinto the center of the spurred wheel S and secures the slide to the ring and the ring to the wheel S. The draft-rod H passes I through the lower end of the slottedbar k, and by loosening the screw it the ends of the draftrod may be set nearer to or farther from the center of the beam G, and by turning the ring S to one side or to the other the line of draft may be changed to the right or to the left of the beam G. This clevis is simple, and when locked up will not be liable to slip.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is i The arrangement of the driving-wheel L, elevating-rod P, swinging rod N, connecting-rod L, crank it, clearer K, beam G, rod H, crankI, spring J, and handles F F, with the plowbody A A B B U D D, as and for the purposes herein shown and described.
